Item 8 Question 1
You ride your bike to school. As you approach an intersection, you decrease your speed by 0.75 mile per hour per second. Select an inequality that represents the time t (in seconds) until your speed decreases by more than 6 miles per hour. Then solve the inequality.

0.75 − t ≥ 6

t − 0.75 > 6

−0.75t ≥ 6

0.75t > 6

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.

Roderick wants to draw a circle for which the numerical value of the circumference is greater than the value of the area. which lengths could he use for the radius? check all that apply
